SMOKING DEVICE Filed Feb. 23, 1962 2 Sheets-Sheet 2 INVENTOR. GEORGE J. SIEGEL ATTO EY United States Patent 3,115,884 SMGKING DEVICE George J. Siegel, PA). Box 62068, Los Angeles, Calif. Filed Feb. 23, 1962, Ser. No. 175,257 2 Claims. (Cl. 131207) This invention relates to a smoking device and more particularly to an attachment for a smoking device such as a pipe, cigarette holder, cigar holder, or the like, for the purpose of by-passing smoke from the stem to pass through a removable filter underlying the stem for filtering out tars or other undesirable fractions from the smoke prior to reception thereof in the mouthpiece of the smoking device.

More specifically, this invention provides a new and improved smoking appliance which may be incorporated with the tubular stem communicating between the bowl of a pipe or other source of smoking tobacco and the mouthpiece to provide a new and improved smoking device for by-passing the smoke through a filter underlying the stem for removal or substantial reduction of unwanted tars and other fractions of the smoke prior to reception of the smoke by the mouthpiece of the device. The by-pass device is securable to underlie the stem of the smoking device and in such manner that the filter is readily and easily positionable into a smoke by-passing position and into a position clear of the stem where it may be easily and readily removed for cleaning and/ or replacement. The stem is constructed with the filter in underlying relationship thereto so as to more advantageously trap the unwanted tars and other fractions, such tars being substantially the heaviest of elements found in the smoke and therefore more readily retained by the filter than has been previously accomplished by other by-passing and filter means which, in the past, have been installed either in coaxial relationship to the stem passageway or in spaced elevated relationship thereto.

This application is a continuation-in-part application of my co-pending application entitled Smoking Appliance, Serial No. 121,783, filed July 7, 1961, now abandoned.

It is therefore an object of this invention to provide a new and improved smoking appliance which is readily adaptable to present designs of smoking devices such as pipes, cigarette holders and the like.

Another object of this invention is to provide a smoking appliance having new and improved by-pass means which is readily adaptable for receiving a removable absorbent filter.

Yet another object of this invention is to provide a new and improved smoking appliance having a removable filter which is readily positionable in underlying relationship to the stem thereof to by-pass smoke from the stem to pass downwardly through the filter prior to reception thereof at the mouthpiece for more complete absorption of undesired fractions by the filter.

A further object of this invention is to provide a new and improved smoking appliance which is easily and readily positionable for removing and/or replacing the filter and/or cleaning of the passageway. in which the filter means resides.

Another object of this invention is to provide a new and improved smo (ing appliance which is economical to manufacture and capable of mass production.

A general object of this invention is to provide a new and improved smoking appliance of the character described which overcomes disadvantages of prior means and methods heretofore intended to accomplish generally similar purposes.

These and other objects of this invention will be more apparent from the following detailed description, drawings and appended claims.

FIGURE 10 is a fragmentary, vertical cross-sectional view similar to FIGURE 8, showing another modification thereof wherein the modification of FIGURES 8 and 9 is shown as being adapted for use as in the construction of a pipe.

Referring in detail to the drawings, and more particularly to FIGURES 1-3, inclusive, there is shown by way of illustration, but not of limitation, a first embodiment designed and constructed in accordance with this invention and generally designated by the numeral 10. The appliance of the embodiment 10 is illustrated as being adapted for use with a smoking pipe generally designated by numeral 11 and including a tobacco bowl portion 12 forming a receptacle 13 for tobacco, a tubular member 14 serving as a stem and having a longitudinal passage 16 communicating betweent the receptacle 13 and a mouthpiece 17 for drawing tobacco smoke from the bowl 12 to the mouthpiece 17 when the tobacco is lit.

The pipe 11 may be conveniently formed in separable sections for convenience of manufacture and of cleaning wherein the mouthpiece 17 is separable from the tubular member 14 by virtue of a sliding or optionally threaded telescopic fit as indicated at 18 and a similar connection in the portion 19 for joining tubular member 14 to the bowl 12.

The pipe 11 may be conveniently formed in separable sections for convenience of manufacture and of cleaning wherein the mouthpiece 17 is separable from the tubular member 14 by virtue of a sliding or optionally threaded telescopic fit as indicated at 18 and a similar connection in the portion 19 for joining tubular member 14 to the bowl 12.

In the first embodiment 10, the tubular section 14 is shown as having a barrier 21 formed integrally therewith so as toblock the passage 16. It is to be understood, however, that the barrier 21, as illustrated in FIGURE 5, and indicated at 21', may be formed separately from the stem 14 to extend through a bore 22 extending through the section 14 and having a relatively air-tight fit with the barrier 21 to intercept the passageway 16.

Returning now to the first embodiment 10, a pair of longitudinally spaced radial apertures 23 and 24 extended through the wall 26 of the tubular member 14, one on each side of the barrier 21 and having axes on a substantially common longitudinal plane so as to communicate between the longitudinal bore 16, on each side of the barrier 21 and the exterior of the tubular member 14.

A by-pass member, generally designated by the numeral 27, is substantially elongated in configuration and is rotatably mounted to the stem 14 in underlying relationship thereto so as to be selectively positionable to the position indicated in solid lines in FIGURES 13, inclusive, wherein the by-pass member is substantially parallel to the stern section 14 and into a transverse position, indicated by the broken lines 27' of FIGURE 2, for a purpose to be hereinafter described.

The by-pass member 27 includes a body 28 having a relatively fiat upper face 29 in face-to-face relationship to a corresponding relatively fiat lower face 30 longitudinally formed on the wall 26 in a longitudinal plane with which the apertures 23 and 24 communicate. The by-pass member 27 includes a pair of longitudinally spaced openings 31 and 32 communicating with the relatively fiat face 28 and a passageway 33 communicating between the openings 31 and 32. The openings 31 and 32 are substantially complementary to the apertures 23 and 24 so as to communicate therewith when the by-pass member 27 is positioned in the longitudinal position indicated in solid lines. In this position, smoke passing through the longitudinal passage 16 is diverted by the barrier 21 to flow through the aperture 23, into the opening 31 aligned therewith, through the passage 33 and outwardly of the opening 32 which is registered or aligned with the aperture 24 and then to continue on through the passageway portion 16 on the other side of the barrier 21 to communicate with the mouthpiece 17.

In the instant embodiment, the by-pass member 27 is rotatably secured to the stem portion 14 by a fastener member 34 having an enlarged head 36 embedded in an upper wall portion 37 of the member 27 and a shank portion 38 rotatably engaging a radial, internally threaded bore 39 extending into the barrier 21 and communicating with the relatively flat face 29 of the section 14. The shank 38 of the fastener 34 is preferably externally threaded for engagement with the internal threads of the bore 39 whereby the by-pass member may be securely fastened to the section 14 through the screw thread connection yet is rotatable relative thereto to position the by-pass member in either the solid line position 27 or the broken line position 27'.

A filter means, generally designated by the numeral 41, is provided for occupying the passageway 33 of the bypass member 27 so as to filter undesired elements and fractions of the smoke passing through the passageway 33. The filter means 41 is preferably a removable type wherein an absorbent material 42 such as cotton, or other similar fibrous absorbent material 42 is encased by a cloth or other porous tubing 43 whereby the absorbent filter 42 may be easily and readily removed from the passageway 33 when the by-pass member 27 is in its transverse position 27' wherein the openings 31 and 32 are exposed. The tubular casing 43 is preferably loosely woven or otherwise formed so as to prevent fibers 42 from being carried by the stream of the smoke yet is sufficiently porous so as to allow free flow of the smoke therethrough without appreciably hampering the flow of the smoke. A convenient filter 42 may be formed by encasing fibrous material such as cotton or the like in tubular casing 43 of cheese cloth or other loosely woven or porous material. In this manner the entire filter 41 may be easily and readily inserted into the passageway 33 or removed therefrom when the by-pass body 23 is rotated in transverse position relative to the stem 14 for cleaning and/ or replacement.

As smoke passes through the filter, the tars and other undesired fractions of the smoke tend to flow along the bottom of the filter, being substantially heavier than the other elements comprising the smoke, and therefore are more completely retained in the filter. The heavier elements of the smoke are deposited in the filter whereas the more desirable portions of the smoke continue through the aligned openings 32 and 24 to pass into the mouthpiece bore 16 for a more satisfactory smoke.

Referring more particularly to FIGURE 4, another embodiment of this invention is illustrated and generally designated by the numeral 10a and in which like parts are referred to by like numbers. In the instant embodiment, the stem 14 is provided with an integral barrier means in the form of a web 21 to intercept and block the longitudinal passageway 16 extending therethrough. The stem 14 includes spaced apertures 23 and 24 provided with one on each side of the barrier 21, similarly to the first embodiment. In the second embodiment, however, the by-pass means, generally designated by the numeral 27a, is yieldably and rotatably secured into the stem portion 14 so as to be rotatable relative thereto but yieldable for lateral movement relative to the stem.

The by-pass member 27a, similar to the by-pass element 27 of the first embodiment, includes an elongated body 28 having a relatively flat upper face 29 coincident with a relatively fiat lower face 30 of the stem section 14 and in. face-to-face relationship therewith. A body 28a further includes a passageway 33 communicating between openings 31 and 32 which are complementary to the apertures 23 and 24 and alignable therewith in a manner similar to that described in the first embodiment. The body 28a further includes an upwardly extending tubular post 44 having a rotating fit in an axial bore 46 formed extending into the barrier 21 and terminating in a blind shoulder 47. The post 44 includes a substantially coaxial internally threaded hole 48 in which an externally threaded shank 49 of a fastener 51 is threadedly engaged. The fastener 51 includes an enlarged shank 52 slidably disposed in a reduced bore 53 and has an enlarged head 54 slidable in a counterbore 56 with one end abutting the underside of the enlarged head 54 of the fastener 51 and another end 'bottomed in the counterbore 57 to bias the enlarged head 54 upwardly and outwardly of the counterbore and, by virtue of the threaded engagement 49-48, biases the shank 44 upwardly and the relativelyfiat face 29 of the body 28a into face-to-face relationship with the relatively-flat face 30 of the stem 14. A peripheral ridge 58 is preferably formed to surround the relatively flat face 29 when the body 28 is in its longitudinal position with its openings 31 and 32 aligned with the apertures 23 and 24 respectively. The ridge 58 serves to index the body 28a to the stem 14 in a longitudinal position and to efllect an improved seal around the body so as to prevent smoke from escaping from therebetween.

In the instant embodiment, to rotate the member 28a into a transverse position similar to the broken line illustration 27 of the FIGURE 2, the body 28a is initially, by either grasping the body and pulling downwardly away from the stem 14, or by pressing on the enlarged head 54 the fastener 51, to cause the spring 57 to yield, is laterally moved relative to and away from the stem 14 as indicated in broken lines 28b to clear the ridge 58, after which the body 28 may be conveniently rotated to the transverse position wherein the openings 31 and 32 are exposed for inserting or removing the filter member 41.

FIGURE 5, as previously mentioned, illustrates a means whereby the barrier 21 may be added to an exist ing pipe or other stem 14' by the provision of a transverse hole 22 through which the barrier 21 extends. The barrier 21 is preferably positively secured in the hole 22 so as to prevent transverse movement of the barrier relative to the stem. For this purpose, barrier 21' is preferably provided with an annular lip 61 fitting in a recess 62 provided in the relatively flat face 30 of the stem 14' and a retainer member, as for example a split ring, 63 is received in an annular groove 64 at an opposite end of the barrier 21 as illustrated. Additionally, cement or other adhesive is preferably provided in the bore 22 to prevent leakage of smoke past the barrier 21 through the bore 22. In all other respects, the by-pass member a and the securement means therefor, in the form of fastener 51 is similar to that illustrated in FIGURE 4, or optionally as illustrated at 34 in FIGURES 1-3, inclusive.

FIGURES 6 and 7 illustrate the adaption of the present invention to a cigarette holder generally designated by the numeral 70. In the instant embodiment, the cigarette holder 70 is provided with a mouthpiece 71, similar to the mouthpiece 17 and having a stem portion 72 similar to the stem portion 14 but having an open end 73 forming a socket in which a cigarette, indicated by the numeral 74, may be conveniently supported. A by-pass means, indicated by the numeral 75, is preferably, as illustrated, similar to the bypass means of FIGURE 4 and rotatably secured thereto as by the fastener 51 or optionally in the form of the by-pass means of FIGURE 3, or of FIGURE 5, so that the smoke from the cigarette 74 passes, as indicated by the arrowed lines 77, around the barrier 78, similar to the barriers 21 or 21 to flow through the by-pass member 75 and thereby through the filter means indicated by the numeral 41 and subsequently to the mouthpiece 71.

Referring more particularly to the FIGURES 8 and 9, another embodiment of this invention is illustrated and generally designated by the numeral 80. In the instant embodiment, a stem 81 is illustrated as being adapted to be used as a cigarette holder similar to the embodiment of FIGURES 6 and 7, and is constructed so as to comprise a pair of axially separable stem elements 82 and 83 which are separable along a transverse parting plane 84 intermediate of the ends 86 and 87 of the stem. The stem portion '86 is adapted to receive a source of smoking tobacco, namely the cigarette indicated by the broken lines 88 of FIGURE 8, which may be seated in a socket 89 preferably having a metallic, or other, liner 91, in the event that the stem comprises a meltable material such as plastics. The socket 89 is coextensive with a longitudinal bore 92 communicating with the open end 86 of the stem element 82 and terminates in a web 93 which blocks the passageway 92 from a substantially coaxial bore or passageway 94 formed in the stern element 83. A substantially reduced bore 96 communicates between the bore 94 and the open end 87 of the stem element 83 for use of the element 83 as a mouthpiece.

A by-pass member, in the form of a protrusion 97 is formed to underlie the stem 83 and has a by-pass passageway 98 formed therein substantially parmlel to the bores 92 and 94 and communicates with the bores 92 and 94 by transverse passages 99 and 101, respectively.

An absorbent filter 102, similar to the filter 41 of the previous embodiments, is adapted to reside within the passageway 98 for absorbing tars and other undesired fractions of smoke passing from the bore 92, through the passage 99, into the by-pass passageway 102. The filtered smoke exits from the passageway 98 through the passage 101 into the bore 94 to be drawn by the mouthpiece through the bore 96 communicating therewith.

Releasable holding means are provided for releasably holding the stem elements 82 and 83 in assembled relationship. The releasable holding means includes a boss 103 axially insertable into the stem portion 83, or, more specifically, into a counterbore 104 of the bore 94 for holding the elements together with the bore 94 being blocked by the boss 103. Further construction of the releasable holding means includes a tubular extension 106 extending outwardly from the parting plane 84 of one of the elements 82 or 83, such as the stem element 82 illustrated herein, and insertable into the by-pass passageway portion of the other element, such as the stem element 83, or more particularly into a counterbore 107 coaxial with the passageway portion whereby the passageway portions of the protrusion 97 are made coextensive and in communication. The tubular extension 106 is axially insertable into the bore 107 in response to axial insertion of the boss element 103 into the counterbore 104 thereby to simultaneously align the portions of the bypass passageway 98 when the stem elements 82 and 33 are assembled.

When the stem elements 82 and 83 are separated, as best illustrated in FIGURE 9, it will be noted that the filter element 102 is partially exposed so as to facilitate removal thereof from the bypass passageway 98 and replacement of a new filter like 102 therein. Furthermore, when the stem elements 82 and 83 are in their separated condition, the passageways 99 and 10-1, the by-pass passageway 98, and bores 92 and 94 are more easily and more readily cleaned.

In FIGURE 10, another embodiment of this invention is illustrated and generally designated by the numeral 110 in which the stem 111 is substantially similar to the stem 81 of the embodiment of FIGURES 8 and 9 but which is adapted for connection as to a stem 112 of a pipe bowl (not shown) for communication of the bore 92 with a bore 113 communicating with the bowl of the pipe so as to communicate the source of smoke from the pipe tobacco therein to the bore 92. In all other respects, the stem 111 of FIGURE 10* is substantially similar to that of the stem 81 embodiment of FIGURES 9 and 10 and like parts thereof are referred to by like numbers.

While there is herein shown and described what is conceived to be the most practical and preferred embodiments of this invention, it is recognized that departures may be made therefrom within the scope of this invention which is not limited to the details disclosed herein but is to be accorded the full scope of the claims so as to embrace any and all equivalent devices.
